I love Corinto Quartz. It is very clear, and always carries a very high vibration. It seems to me to be a message of hope from Mother Earth.
These crystals have been put into a separate category because they each carry, in addition to the energy of Corintos, a special energy of their own. Whether it is the unique formation, the rainbows throughout, or just a powerful energy that radiates outward, these stones can be used as ceremonial or healing crystals of the highest order.
